This address must correspond to the location 16 of the udma_addr0 section in the linker script for the dma0 node, and the udma_addr1 17 section for the ulpdma node. Ensure that the value specified for the SRAM address matches 18 the respective section defined in the linker file for each UDMA node, as this alignment 19 is critical for proper descriptor management and data transfer. 20 21 "#dma-cells": 22 const: 1 23 24# Parameter syntax 25dma-cells: 26 - channel 27
